A mysterious entry jumps out from the US Department of Energy report covering emergencies and disturbances for Q1 2019. Without going into any detail, it simply notes that between 9:12 AM and 6:57 PM on March 5 the power grid suffered a “cyber event that causes interruptions of electrical system operations.” Areas affected include Kern County and Los Angeles County in California, Salt Lake County in Utah, and Converse County in Wyoming.
